Ok my car used to have this little problem where shortly after starting (up to 5min) if i let the car rev down the rev range coming up to the lights or something, slow engine braking, the engine light would come on sometimes and give a code 1, the o2 sensor.
It never gave any negative effects. It just came on and i'd turn the key off and on and keep driving and it wouldnt come on again. I just had a few other probs with my distributor dying and had the o2 sensor changed as we found out it was a holden o2 sensor (wtf...). So now after a full service 2 weeks ago and having a new distributor, ignition leads, plugs and o2 sensor everything should be sweet right.
I had been engine braking up to lights slowly after starting the car for the last few days after getting my car back with no problems, then today as i was slowing down just as i started putting the clutch in the engine light came on and it was a code 1 again.
Now i think my injectors may be dirty as the car splutters a bit at startup, which clears up after a few seconds and the idle smooths out and the car runs fine. I originally thought that problem was caused by the faulty distributor but the only other thing i can think of is a fuel delivery problem. The car is a b16a with a chipped p30 ecu. I got some injector cleaner which i'm gonna put in tomorrow and i'll reset the ecu as well afterwards. I'll get the injectors and fuel pump checked next week when i get a bit more dosh but has anyone got any input about the o2 sensor and if they think it could be caused by a fuel delivery problem with it only happening at low rpm and just after startup?
